No way to test! Tubes have slight rattles in them. Used in Ham Radio, Induction Heaters, Plasma Generators, RF Generators and much more. Link to datasheet: http://catalog.rell.com/rellecom/Images/Objects/3500/3495.PDF The BURLE 8977 is intended specifically to meet the high gain, aural requirements of modern, reliable, VHF-TV. In VHF-TV aural service at 216 MHz, the tube will deliver a full 7.0 kW output at 19 dB gain. Rated for full input for the VHF-TV band and for other services to 409 MHz, the tube can be readily circuited for these frequencies. The tube and available variants are also well suited for other applications such as Single Sideband CW, pulsed RF or modulator service. Its sturdy, CERMOLOX construction and thoriated tungsten, mesh filament minimize tube inductances and feed-thru capacitances. Its coaxial, forced-air-cooled radiator reduces noise to a minimum and insures against spurious outputs. These features make possible the use of simple, economical, and broadband circuit techniques in VHF and UHF operation. * 7 kW Aural Output Through VHF-TV Band Amplification Factor (µ): 20.0 Filament Current (A): 115.000 Frequency (MHz) Maximum: 400 Peak Anode Voltage (kV): 13.000 Peak Cathode Current (A): 6.000 Typical Anode Current (A): 1.320 Typical Anode Dissipation (kW): 6.000 Typical Anode Voltage (V): 8,200 Typical Power Out (kW): 7.000 (We do not proofread any ads submitted by members) |
